New to VBA

OK, I know I'm new to this and really making a big attempt to learn it but I
am getting confused on a few things.

1. I'm trying to create a routine to change layer, should be a simple thing
to learn with, but I have the...
Dim ss As IAcadSelectionSet
Option Explicit

Set ss = ThisDrawing.SelectionSets.Add("NEWSS")
ss.SelectOnScreen

in the Module1 (code) and I'm trying to do something with it in the
UserForm1 (code).
But it says it's not defined. Even though I defined it in the code before it
gets to the point of stopping.

Can you only set a variable to work in the (code) that you are referencing
it in?

I hope I'm making sense of this.

2. Another problem I'm having is when I run this and it stops and then I try
to run it again it's telling me...
"The named select set exist" Can you create the code to clear the value of
ss if you run it again?

You need to read up on Variable Scope. In extremely simple terms, if the
module is calling the form, then you can use Public or Private to declare
the variable and make it available to both. You can also pass it from place
to place.

When your program is done, issue a ss.Delete. It s also a good idea to
check the selectionset collection of the drawing to make sure the name of
the selection set is not already in use before you try using it.

You should try going to your local library and signing out a copy of VBA
For Dummies or some other such title. While its not AutoCAD related, it'll
help get you up to speed on how VBA works. I like the library best so you
don't have to make an initial investment - save that for a good AutoCAD VBA
reference book =)

Kevin, look into the acad help file. Here you will find the "ActiveX and
VBA Reference" section. From there look in the "Code Examples" section.
There is a wealth of information there.
